Per Bug 1609068 Comment 16,

XBOX_ONE_S USB controller will be disconnected when it queues too many events, like pushing up its joysticks and keeping it about 20 seconds. After decreasing the delay of kDarwinGamepadPollInterval, the situation can get better. I feel giving 50 ms is not right, for normal video games, they need at least 60 HZ (16 ms). If we give it 50 ms still, users would feel delay for sure, after including the delay from IPC between the content and parent processes. The issue would be worse.

After experiments, if giving 0 delay to XBOX_ONE_S USB, we will never see this disconnect issue again. Let's try to use other small number to replace 50 ms first.
